steelResults of a study of the effect of the initial structure (granular and lamellar pearlite) of medium-carbon alloy steel 45KhN2MFA-Sh used for the production of torsion shafts on its deformability and hardenability in the process of preliminary thermomechanical treatment (PTMT) involving cold...
The paper discusses the influence of the initial parameters on the strength parameters of S235JR steel at low stress triaxiality. The analysis was performed using the Gurson-Tvergaard-Needleman (GTN) material model, which takes into consideration the material structure. The initial material porosity ...

Mechanical propertiesFatigueAn EA4T steel billet was forged at the different initial forging temperatures (1050, 1150, and 1250 掳C). The microstructure and fatigue fracture of forged samples were observed by laser scanning confocal microscopy and scanning electron microscopy, respectively. The fatigue ...
HSLA Steelinitial microstructuremechanical propertiesrecrystallizationHigh Strength Low Alloy Steel (HSLA0) with different initial microstructures (Ferrite and Martensite) was processed by cold rolling at room temperature to the reduction of thickness about 70%. It was found that the recrystallization ...
The effect of the initial microstructure of low-alloy tube steel 13KhFA on its mechanical properties after quenching from the intercritical temperature range (ICR) has been studied. It has been established that the maximum impact toughness KC V-80 is achieved in the case of the initial quenched...
Effect of initial martensite and tempered carbide characteristics on mechanical properties of 3Cr2MnNiMo mold steel were investigated. The results indicated that the initial martensite microstructure can be effectively adjusted by changing the quenching temperature. With the increase of quenching temperature ...
The paper deals with materials properties of steel bends. Tubes and pipes, respectively, of P92 steel were hot and/or cold bended. Moreover, the various combinations of tubes/pipes dimensions were chosen. Then, as-bended steel was exposed to a long-term temperature and/or mechanical loading....
The effects of different initial microstructures on the microstructural features, mechanical properties, and fracture appearance of a C–Mn dual phase (DP) steel are studied. It is revealed that the martensitic and normalize initial microstructures result in excellent combination of strength and ...
